What this test measures
HOMA-IR is a number calculated from a fasting glucose and a fasting insulin result taken from the same blood draw, using a published formula called the homeostatic model assessment. It is an index rather than a direct measurement, so it has no physical unit, and it is used as an estimate of insulin resistance.

Why the same lab printed a different reference range for you this year
Ranges are not fixed constants. The lab can change method, revise its reference group, or apply a range that depends on your age — none of which is an error.
